Usually a female, who has odd fetishes for raw sushi to be thrown on her body. (Particularly head/hair) in which she recipricates by chasing culprit into Male toilets and raping them several times before murdering them and dumping their body in a river. Returning regularly to feed off the rotting corpse.

As i was walking past a school i noticed Cherylanne covered in sushi and running to a Male bathroom chasing someone.

OMG she totally did a cherylanne with that hot guy last night.

They found a body in a lake and suspected another Cherylanne had done it.
